How to increase/reduce the fontsize of X and Y tick labels in Matplotlib?
To increase/reduce the fontsize of x and y tick labels in matplotlib, we can initialize the fontsize variable to reduce or increase font size.
Steps
Create a list of numbers (x) that can be used to tick the axes.
Get the axis using subplot() that helps to add a subplot to the current figure.
Set ticks on x and y axes using set_xticks and set_yticks methods respectively and list x (from step 1).
Set tick labels with label lists (["one", "two", "three", "four"]) using set_xticklabels() and set_yticklabels() with fontsize variable.
To add space between axes and tick labels, we can use tick_params() method with pad argument that helps to add space. Argument direction (in) helps to put ticks inside the axes, and axis (both), parameters to be applied on both the axes.
To show the figure, use plt.show() method.
Example
from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = [1, 2, 3, 4] ax1 = plt.subplot() ax1.set_xticks(x) ax1.set_yticks(x) fontsize = 15 ax1.set_xticklabels(["one", "two", "three", "four"], fontsize=fontsize) ax1.set_yticklabels(["one", "two", "three", "four"], fontsize=fontsize) plt.show()
